FERRULE FOR CANT-HOOKS.

SPECIFICATION forming part of Letters Patent No. 228,943, dated June 15, 1880.

Application filed January 13, 1880.

To all whom it may concern Be it known that I, ALBERT SANFORD, of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented certain new and useful Improvements in Ferrules for Gant- Hooks and other similar Implements; and I do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents a perspective view of the ring or ferrule; Fig. 2, a longitudinal sectional view of the same; Fig. 3, a view showing the manner of securing the ring by Wedging, and Fig. 4 a cross-sectional view of the ring.

Like letters of reference indicate the same parts in the several figures.

This invention has for its object to provide an improved ferrule or toe-ring for pevies, pikepoles, cant-hooks, and other similar implements and it consists, primarily, of a ferrule or toe-ring provided with internal longitudinal ribs or ridges extending from a point at or near the base or larger end of the ring to a point near the smaller end thereof, and terminating abruptly at the latter point, so as to form shoulders, which operate to prevent the detachment of the ring when the latter is in place on the implement and the customary wedges are inserted by sinking into that portion of the wood expanded by the wedging.

It further consists in giving to the ribs or ridges a spiral twist, whereby they are made to take hold like the thread of a screw when the ring is driven onto the implement, and thus form a more secure connection.

It further consists in bevelin g or flaring the ring at its smaller end beyond the shoulders formed by the ends of the ribs; and it consists, lastly, of the ring as a whole, constructed as I will now proceed to describe.

In the drawings, A represents the body of the toe-rin g or ferrule, made preferably of castiron, and of the usual tapering form. B is a series of longitudinal ribs or ridges, preferably four in number, formed upon the interior of the ring and extending from the points 1), near the base or larger end of the ring, to points 12 near the smaller end thereof, where they terminate abruptly and form shoulders, which enter the. wood and prevent the Withdrawal of the ring when the wedges W are inserted in the end of the implement.

The ribs are preferably made of V-shaped form and tapered to a point at their commencement, to facilitate the driving of the ring onto the implement, and they are given a spiral twist in order to render their hold upon the implement more secure, all as plainly indicated in Figs. 1 and 2.

The lower end of the ring, beyond the termination of the ribs or ridges, is beveled oh, so as to permit the expansion of the wood when the wedges are inserted into the end of the implement. Rings thus constructed are easily applied, do not work loose, and cannot be pulled 01f when once fixed by wedging.

I claim as my invention 1. Aferrule or toe-rin gfor pevies, can t-hooks, 850., provided with internal longitudinal ribs or ridges, commencing at or near its base or larger end and terminating in abrupt shoulders near its smaller end, substantially as described, for the purpose specified.

2. A ferrule or toe-ring provided with 1ongitudinal ribs or ridges, which are twisted slightly spirally, for the purpose of taking a more secure hold on the statl' when driven on.

3. A ferrule or toe-ring provided with internal longitudinal ribs or ridges terminating in shoulders, as described, and having its smaller end beveled beyond the shoulders of the ribs, for the purpose specified.

4. The herein-described ferrule or toe-ring, consisting of a single casting, having the internal longitudinal spirally-arranged ribs or ridges of V-shaped form, and having its smaller end beveled or flared beyond the termination of the ribs or ridges, as set forth.

ALBERT SANFORD.
